Northern Diabolo Monitoring, Brussels, Belgium

The Northern Diabolo project spans 6.4km of tunnelled railway, connecting the airport to a Central Brussels. The concession’s 40-year demand-based payment mechanism relies on a supplement paid by each passenger using the service.

Infrata's role:

At bid phase, the Infrata team conducted full technical, traffic and revenue due diligence for the successful consortium’s lenders. Our technical assessment included an in-depth review of the site’s geotechnical conditions, the consortium’s construction plan, and its ability to operate and maintain the asset.

The traffic and revenue analysis involved a traffic forecast for Brussels Airport, a surface access model, and a corresponding revenue projection.

Our team was retained as traffic, revenue, and technical monitoring advisor throughout the four-year construction phase. During this time, Infrata undertook regular reports and site visits on behalf of the project’s lenders. We have since served as operations monitor.

“The funding for this project has been highly innovative, with revenues generated throughout the design and construction period by means of a Diabolo supplement paid by each passenger travelling on the existing rail link.
“The success of this initiative demonstrates the opportunities that exist for blending different funding streams to aid investment in critical infrastructure.
”
